New features to 5.00
- read the doc! almost everything's new.

Bug fixes to 5.00:
- recursive wild card expansion does not crash the Amiga 3000 anymore
- recursive wild card expansion does not lose memory anymore
- now works on AUX:
- trying to start a non-object-file now properly prints 'Command Not Found'
- automatic sourcing now also works if you already add .sh to the file name
- files longer than 999999 bytes no longer misalign 'dir'
- exec does not discard the rest of the command line ('exec echo hi;echo ho')
- all memory trashing fixed. Thanks to C= for their great debugging tools!
- source doesn't forget last character if batchfile was not CR terminated
- run & rback also search AmigaDOS path now
- division by zero does not crash rpn anymore
- temporary pipe files are now written to t: instead of ram:
- shift-tab does not cause a lockup anymore
- running the shell via aux: no longer crashes the machine
- 'history partial' now numbers the lines correctly
- strleft, strright and strmid no longer crash on strings > 256 bytes
- source with no arguments now prints correct error message
- 'input' now cuts down lines longer than 256 bytes instead of crashing
- cursor-up no more deletes lines if there's an invalid entry in the history
- if history fails, no empty history entry is generated
- 'echo "---"' and even 'echo ---' work, but 'echo "-a"' still doesn't
- international character sets can be used
- 'copy -u' won't copy a file with identical date stamp but in uppercase
- 'copy -u' will no longer access low memory
- 'echo "echo mem | shell" | shell' now works, not only every second time
- starting from workbench now prevented
- editing lines longer than 256 bytes is now correctly prevented
- word-right cursor movement works correclty with multiple blanks
- 'if'-stack will be adjusted when a batch file is exited
- relabel occasionally crashed in Syquest drives. should be okay now

Known bugs in 5.00:
- under 2.0, doing a 'cat' with no args and pressing return will cause a
  character to appear at the right border of the window. seems to be a
  kickstart bug, as it does not happen under older kickstarts.
- AmigaDOS 2.0 CLI commands cannot be made resident. They read their command
  line from stdin. This is definitely a kickstart bug.
- guaranteed to crash in extreme low mem situations
- command line editing doesn't quite work on a (physical) vt100. OK on VT200
- under kick 2.00, fast repetition of ^W crashed. OK under 2.02
- 'set x a b;echo hello$x' still outputs only 'a b'

Incompatibilities in 5.00:
- 'copy -f' now means 'freshen'. Old meaning of -f is now -p (protection)
- '~' at the beginning of a file name must now be quoted
- '@' is the beginning of an argument should be quoted
- 'cat' no longer adds a CR to a non-CR-terminated file
- '0' is now 'false'. Example: 'if 0;e hi;else;e ho;endif --> ho
- variables with comparision operators inside now cause problems in 'if'
- a single '?' will not pattern match, but be passed as a string



New to 4.02A:
- Fixed bug that caused loss of memory on exit.
- cp now copies protection bits; use -f switch if you want to avoid this.
- Added  commands: man (and alias manlist), uniq, head, tail, tee.
- This doc has been reformatted to work with man.

New to 4.01A:
- This version features mostly bug fixes and corrections:
 * Window title is restored after quitting.
 * rxrec now answers to the 'bye' message.
 * rpn can now be redirected and piped; however, this causes
    some problem (see rpn for info).
 * resident list now works with ARP 1.3. To recompile source, you must
    modify include file "libraries/arpbase.h".
    Change definition of rpn_Usage in struct ResidentProgramNode from LONG
    to WORD.
 * pri no more assumes 20 CLI maximum.
 * you can now split long lines in source files even into more than 2 lines.
- Added much info in this doc about source files (chapter XI)
- Added copyright notice (see under restrictions).

New to 4.00A:
- This version is called 4.00A because it is not 100% compatible with
  previous versions. We choose to accept this in order to better support
  the new ARP.library 1.3.
- External commands are searched in a different order than before; Shell
  path is now searched AFTER current directory, AmigaDOS path and C:.
- ARP pattern matching has been implemented (in part for line arg expanding,
  fully for search -w).
- Internal changes for various optimizations.
- Search command has been improved in several ways.
- New commands: basename, tackon.
- New options: if -v, resident -d, fornum -v -s, dir -n.
- Fixed bugs with dir (some dirs remained locked), foreach -v, htype
  (blanks were treated as binary), info (for devices > 32M).
- rback command now works ok (run, however, doesn't).
- Oh, I forgot: it also has an AREXX port... And you don't even have to get
  AREXX to use it. See new commands rxsend, rxrec

New to 3.03A:
- New filter commands fltlower, fltupper.
- Added configuration file feature: now if you have a file named S:.login,
  it will be sourced for every Shell you start.
- New option dir -c.
- New editing feature: shift-left(right) arrow move cursor to previous(next)
  word.
- Bugs fixed: alias command wasn't listed in help; typing a number as a
  command was interpreted like 'alias'.

New to 3.02A:
- New commands: fornum, forline, strleft, strright, strmid, strlen, exec.
- Improved commands: foreach, pri.
- New system variable _clinumber.
- You can now split long lines in source files (see source for details).
- window -q now lists also position of screens/windows, not only dimension.
- Since strings are handled directly from Shell with new commands,
  rpn is now used only for calculations; string commands are gone.
  However, now RPN is really usable.
- Changed rawgets() to fix some problems with function keys, multi-line
  editing and window resizing; also, fixed bug with ^E.
- cat now warns you if it can't find any file matching your pattern.
- Now uses DOS packets to get ptr to CLI window; this fixes a bug that
  caused problems if Shell was run on unactive windows.
- Fixed minor bugs (htype printed some more ASCII bytes, some commands
  returned random values, history didn't print CR's).
